I've never installed a new dump valve and I have never seen instructions for installing them. I have had to take mine apart.

Read it again. I've never installed a new one. But I would guess the instructions that come with one would indicate how tight the bolts should be. I have removed and reinstalled two of them for other issues. And if you over-tighten the four bolts, you will have problems opening and closing the valve.
